My invention relates' to paper making machines, particularly of the Fourdrinicr type.. One of the' objects of the invention is to prevent the wire ot` a Fourf'lrinier nnnfhine from wearing grooves in the suction be); covers, thereby wearing wire andprevcnting proper guiding.

Another object of the invention is to cure this result automatically by the operation of the machine, and furthermore, to secure it by means of the travel of the wire itself. 4 A

Another object of the invention is to se cure the aforesaid results Without the addition of any substantial number of moving parts, and Without encumbering the ma chine with such parts, and without transmitting operating power from one part' of the machine to another. l i

ln the accompanying drawings Fig. lis a side elevation of. a Fourdrinier end embodying,r my invention;

Fig. 2 is an end-elevation of a portiono the mechanism more directly involved in carrying out ,the invention;

Fim?) is a plan view of the same; and

Fig'. l is a side elevation of the same.

Referring to the drawings, I show one type ot Fourdrinier machine for the purpose ot illustrating the invention, although it should be understood that the invention can be applied to various other types land forms ot machine.

ln theinachine shown a table l is provided with a set of table fl, over all ot `vhich the wire 4l travels. Variw ous other` parts ot the machine' are also shown, but all o l them will notbe described as they are not all concerned in the invention.

In order to prevent' the traveling Wire 4 from forming grooves inthe suction box covers, and in order to secure other advantages, arrangement is made for giving the wire L a slight lateral motion from side to side as it travels longitudinally of the machine. This secures the .desired result,"and not only prevents grooving' of the suction box covers, but also prevents 'wearing the wire which would malte guiding dillicult. This lateral or .side lo side movement of the ivire is desir-ably secured automatically by -the operation ot the machine itself, and preferably by means of a Wire roll operated by the travel ot the' Wire.

In the arrangement shojvn, which ot rolls 2--2 and abreast roll course is understood various arrangements tor the purpose, I arrange a Wire roll 6 un derneath table` 1 andniount it so that one end, the nearest end in Fig. 1, may be moved slightly back and iorth in a more orless horizontalnimmer, so that said roll will he inclined to the direction of movement of the wire, first in one direction and then in another direction. This inclination of the roll tirst yto one side and then to thev other side ot a medium line running ydirectly at right angles to the direction ot' travel ol the.; nire, will canse the Wire to move laterallyly lirst in one direction and then in y"anothe i and so cause a slight weaving of the wird hack and orth laterally which will con-"f tinually wary its boxes, thetable and other rolls, and sono to be only one of Vwhich could be used coniplish `the desirable results above set forth. '"i

As one arrangement for securing this swinging or vibratory part 'ot the roll 6, preferably by the travel ot the Wire itself, the swinging or moving en'd of said ro`.l is mounted on a sliding hearing 7 (Figs. 2, 3 and 4), mounted to slide on a more or less horizontal'guide or slideivay 8, and this sliding bearing 7 `is pivotally connected at 9 with abell crank 10, whose other arm 11 is pivotally connected at 12 with a link 134 connected with a crank pin Mon a rotary member or Wheel'l. The latter is carried by a rotary-shaft 16 carrying' a worm wheel 17 which meshesjivith a worm 18 carried by the shatt 19 of said Wire roll G. T he slideway 8 may be mounted on a, suitable frame Sv, and the worm Wheel shaft '1G maybe mounted I l giving the various parts suitable support. By this arrangement vthe rotation of the Wire Wheel 6 by the travel of the Wire will cause the worm 18 to turn worm Wheel 17 and this in turn will rotates'hatt 16 and cause crank pin 14.- to vibrate bell crank 10 and so move slide 7 back and forth on slideway 8, thereby giving the wire roll 6 such a vibratory or swinging movement as will cause it to become inclined firstin one direction an then in another tothe line of travel of the ivire, and so cause the wire to more laterally or from side to side first in one direction and then in another.

From the foregoing Lit will be seen that the Wire is laterally shifted to'secure the desirable results set forth and that this .is

on a suitable stand 2O,l

lWhat I claim is:

l. A ,l."oui'driniei machine having a device operated by the Wire and means whereby said device by its operation continually shifts vthe wire from sidev to side,... 2. A l*`oii1diinicrv machine having a device rotated bv the wire and means whereby u continually shifts 3.- ArFourdriniei' machine 'having' a` Wire .roll mounted to eil'eet a lateral shifting of operated by said roll -for effecting such shifting movement so as wire from side to 4. A Fourdriniery machine having a wire roll mounted for swinging movement' to .cause the lateral shifting movement of the wire and means operated by the rotatio1i. c of said roll l same so as to shift the side to side.

5. A'Fuurdrinier machine having a Wire for lcontinually swinging the Wire continually from 'roll mounted for swinging mcvement'to effeet the lateral shifting movement of,v the wire and means operated bysaid rfollfor eecting such swinging inove-l continually `roll mounted for connected with said crankl ment so as t0 shift the'` vviiiefeontinually ,from side to side.

6; A Al4`ouidi'inier machine havinga wire roll mounted for swinging movement tol effeet the side to side'shifting movement of the l wire and means` operatedl by the Wire for continually effecting such swinging movement of said roll so as to continually shift the wire froinside to side, said means com- 'prisiugir a worin and wheel arrangement ofperated by the roll and means for moving one end of the roll controlled vby said worm and wheel arrangement. v
